Developments for the readout of the PANDA micro vertex detector

The experiment PANDA (Antiproton Annihilation at Darmstadt) is under development for the future accelerator facility FAIR in Darmstadt, Germany. In the target spectrometer of PANDA a micro-vertex detector (MVD) will be used as the central tracking detector for charged particles. The design of the MVD is based on silicon strip detectors at the outer layer and on silicon pixel detectors at the inner layers. The paper discusses the requirements and first concepts of the DAQ system for the MVD which has to be finished about 2015. It presents the design of the lab system that has been developed already now for the test and readout of different frontend chips for pixel detectors. The lab system consists of a flexible readout board coupled via the SIS1100 Gigabit link to PCI. A further improvement of the lab system employing a 2 Gbit/s optical link to PCIe is introduced.
